<p>PURPOSE: A touch sensor system using the vibration of a touched point is provided to accurately find locations of the touched point on a touch plate, thereby simplifying a manufacturing process and reducing a unit cost. CONSTITUTION: First and second sensor bars(11,12) are made of a piezoelectric material, and include lattices(13,14) in one side. A touch plate(20) includes the first and second sensor bars in a horizontal side and a vertical side. A signal processing unit(30) is connected to the first and second sensor bars, and receives an electric signal. A point calculation unit(40) calculates a touch location for the touch plate from the electric signal. The touch plate is manufactured with a material of which the vibration attenuation coefficient is fixed.
